This is backed up by DMC4:SE too. Virgil's appearance in that game is the same as in three, and the opening it says that his exploits took place a few decades before the main game. Assuming "a few" means 2, because 3 decades would make Virgil 9 at the time, then we have DMC4 20 years after 3, making Dante 39 at the time. Jackpot.
